All 401 national parks across the country will have free entrance on Monday, January 21 in commemoration of Martin Luther King, Jr. Day.

Get outdoors and celebrate Martin Luther King, Jr. Day by taking advantage of free admission to all 401 national parks in the United States.

“National parks are well-known for scenic beauty and outdoor recreation but they are also fantastic places to learn about the people and events that have shaped our nation,” says National Park Service Director Jonathan B. Jarvis. “Historic sites, battlefields and memorials across the country preserve the places and tell the stories of our national struggles and accomplishments. I encourage everyone to take time to visit a national park on Monday, especially one of the many dedicated to Dr. King and the Civil Rights Movement.”

In addition to Martin Luther King, Jr. Day, the National Park Service will also waive admission fees on 8 other days in 2014—Presidents Day weekend (Feb. 15-17), the first weekend of National Park Week (April 19 and 20), the National Park Service’s 98th birthday (Aug. 25), National Public Lands Day (Sept. 27), and Veterans Day (Nov. 11).

National park passes that provide free or discounted admission are available for active duty military members and their dependents, senior citizens, and people with permanent disabilities.
